Personally, I've reverted back to v3.1 for now. v4.1 is an absolute battery killer. It's okay when idle but when in use it's like you're constantly playing 3 games at once. I literally watched the battery drop 3% whilst just scrolling around my apps and home screen. I've lodged the extreme battery use with the dev, so hopefully he can find whatever he changed between 3.1 and 4.1 that uses so much juice.
It's funny because v3.1 has the best battery life i've ever had and v4.1 has the worst!
UPDATE: As I posted, adesirello has updated his OP with a changelog for v5.0 to be released in a few hours! It promises battery saving! We shall see
It's based on the new, supposedly even more stable LPB rom released a couple of days ago by sammobile!
